Kugwirizana kwapolycarboxylate superplasticizerndi zosakaniza zina

polycarboxylate superplasticizerndipo ma superplasticizers ambiri sangasakanizidwe ndikuphatikizidwa mugawo lililonse ngati naphthalene ndi aliphatic superplasticizers. Mwachitsanzo, zotsatira zoyipa pakusunga kutsika kwa pulasitiki ndizokulirapo pamene polycarboxylic acid ndi naphthalene water reducer ziphatikizidwa, ndipo chidwi chapadera chiyenera kuperekedwa. Izi zapangitsanso opanga ambiri ochepetsera madzi a polycarboxylate kuti apangitse zakumwa zoledzeretsa za amayi ndi ntchito zosiyanasiyana zapadera monga kusungitsa kugwa komanso mphamvu zoyambira kuti zigwirizane ndi zosowa zamamangidwe a konkire munyengo zosiyanasiyana, zida ndi kusakanikirana kosakanikirana, ndipo pamapeto pake akwaniritse zotsatira zogwira mtima. Komabe, kaphatikizidwe ndi kagwiritsidwe ntchito ka mowa wamayi kumafuna nthawi yayitali, ndipo mtundu umodzi wa zakumwa zoziziritsa kukhosi sungathe kuthetsa mavuto ambiri pakugwiritsa ntchito uinjiniya wa superplasticizers. Ndi chowonjezera chofunikira pakugwiritsa ntchitopolycarboxylate superplasticizer, ndipo ndizofunikira kwambiri kuthetsa mavuto aukadaulo omwe amakumana nawo pamalo opangira uinjiniya kudzera muzochita za mowa wa mayi ndi chiwembu chophatikizira chakuthupi chazinthu zazing'ono. Ndi bwino kugwiritsa ntchitopolycarboxylate superplasticizerkuphatikiza ndi zigawo zina. Onetsetsani kutsimikizira zotsatira za compounding ndi mmene kwenikweni pa konkire kudzera mayesero, ndiyeno kuweruza ngatipolycarboxylate superplasticizerakhoza kuphatikizidwa ndi zigawo zina.

Kusunga mildew vuto lapolycarboxylate superplasticizer

Pamene apolycarboxylate superplasticizerzimasungidwa nyengo yotentha kwambiri m'chilimwe, zochitika za mildew monga kutulutsa fungo loyipa, kuphulika kwa migolo yomata yomata, mawanga oyandama pamadzi amadzimadzi mu thanki yosungiramo yotseguka, komanso zinthu zoyandama zoboola pakati nthawi zambiri zimachitika. Chifukwa chachikulu ndi chakuti ndondomeko yonse yapolycarboxylate superplasticizerkuchokera pakupanga kupita ku ntchito ndi kumwa kumasungidwa mu chikhalidwe cha bakiteriya, pomwe zinthu zomwe zimagwiritsidwa ntchito mochedwa kwambiri monga shuga ndi hydroxycarboxylates zimapereka bowa. Zakudya zabwino kwambiri, m'malo oyenera kutentha ndi chinyezi komanso pH yopanda ndale, kuchuluka kwa bowa kumawonjezeka kwambiri. Pambuyo pa kufa kwa bowa, mitembo yambiri imasiyidwa, zomwe ndizomwe zimayambitsa mildew.polycarboxylate superplasticizer. Choncho, yogwira zosakaniza mu mildewedpolycarboxylate superplasticizersizikukhudzidwa kwambiri, ndipo magwiridwe antchito ndi okhazikika.

The mildewedpolycarboxylate superplasticizerali ndi fungo lamphamvu komanso chithovu chochuluka pamwamba, chomwe sichithandiza thanzi la ogwira ntchito komanso kuyeza kolondola kwa superplasticizer. Ndikofunikira kuchitapo kanthu kuti muchepetse. Pakati pawo, njira yothandiza kwambiri ndikusakaniza ma bactericides kuti akwaniritse zotsatira za bacteriostasis ndi kulera. Panthawi imodzimodziyo, njira monga kusintha pH ya madzi ochepetsera madzi kuti ikhale yopanda ndale (pH≤3. kapena pH> 9.0) ndikusintha mtundu wa retarder ingagwiritsidwenso ntchito.
